CUTTER FOR GREEN-CORN-CUTTING MACHINES.

Application filed October 16, 1913.

To all whom it may concern Be it known that I, JOHN M. C. JoNEs, acitizen of the United States, residing at Onarga, in the county ofIroquois, in the State of Illinois, have invented certain new and usefulImprovements in Cutters for GreenCorn-Cutting Machines, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to cutting devices for green corn cuttingmachines, and has for one of its principal objects the provision ofcutting devices capable of adjusting themselves to work upon ears ofdifferent sizes.

ItIeretofore it has been customary to use two oppositely disposed curvedblades between which the ear of corn has been forced, passing thence totwo oppositely disposed curved blades positioned at approximately rightangles to said first-mentioned blades. It has been found that cuttingdevices of this type will do clean work only upon cobs of approximatelythe diameter of the normal opening between the blades.

By my invention I have provided a construction of cutting device whichwill do clean work whatever the size of the ear of corn, this beingaccomplished by the use of straight blades as hereinafter described inplace of the curved blades heretofore used.

By the use of straight blades arranged in accordance with my invention Iam enabled to place the spur rollers, by which the ear is forcedforward, closer to the blades thus securing a better and more positivefeeding of the ears.

Another advantage resulting from the use of my improved construction isthe greater ease with which the blades can be sharpened.

It is another object of my invention to provide a construction in whichthe cutting blades are readily removable from the machinefor repairing,sharpening or cleaning the blades.

It is another object of my invention to improve devices of this generaltype in sundry details hereinafter pointed out.

The means by which I have accomplished my objects are illustrated in thedrawings and are hereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the drawings,Figure 1 is a side view of one of the removable bracketssupporting one pair of oppositely-disposed blades Specification ofLetters Patent.

in operative position, the spur rollers which would be used adjacent tosuch blades being shown diagrammatically in therewithfFig. 2 is anenlarged detail, being substantially a cross section on line 2-2 of Fig.1; Fig. 3 is a top view of the bracket shown in Fig. 1 with the cuttingblades removed therefrom; Fig. I is a View of the bracket of Fig. 1 withone of the blades removed therefrom; Fig. 5 is a View of the bladeremoved from the bracket of Fig. i; Fig. 6 is a viewof the completecutting system showing four pairs of cutting blades in operativeposition relative to each other, the spur rollers which would normallybe used in connection with such cutting system being omitted for thesake of clearness of illustration; and Fig. 7 is a modification showingthe mounting of two pairs of blades upon a single bracket instead ofupon two brackets as shown in Fig. 6.

' Referring to Figs. 1 to 6, in which corresponding parts are indicatedby the same reference characters,10 indicates a bar extendinglongitudinally of a green corn cutting machine, and 11 indicates a plateat a convenient distance from the bar 10 and extending paralleltherewith. My improved cutting device is designed for use perferablywith a green corn cutting machine of the type shown in United StatesPatent, No. 1,037,01 l, issued to me on August 27, 1912. It will beunderstood that my improved cutting devices of the type herein shown areto be substituted for the blades 8299 and 122123 of the patentedmachine, such patented machine being changed as necessary to adapt it tothe use of my improved devices as will be readily understood. The bar 10and plate 11 for supporting my improved cutting devices will be suitablypositioned in the patented machine parallel to the present position ofthe plates 112113 of such machine.

Referring particularly to Fig. l, 12 indicates a bracket provided with asocket 13 at one end adapted to have a working fit upon the bar 10 so asto be readily removable therefrom. The opposite end of said bracket 12is cut away at its central portion forming ears 1415 which fit betweenguides 1617 and on opposite sides of a longitudinally-extending rib 18formed upon one face of the plate 11. It will be understood that thebracket 12 is thus rendered easily removable from the machine connection7 by merely lifting the left hand end of such bracket from the bar 10whereupon the bracket is capable of being moved longitudinally of itselfout of engagement with the plate 11.

As best shown in Fig. 3 the bracket 12 is provided near one end with aboss 19 and two studs 20-2l. Upon the studs 2021 are rcvolubly mountedarms 22----23, respectively, being held in position on said studs bymeans of a plate 2% which is pivotally mounted upon the boss 19 by meansof a screw As best shown in Fig. f when the screw 25 has been loosenedand the plate 24 has been turned to the left the arm 28 can be liftedreadily off of the stud 21, and it will be understood that when theplate 24; is turned to the right in said Fig. l the arm 22 can likewisebe readily lifted from the stud 20.

Each of the arms 22-23 is provided with a set-screw 26 adapted to beadjusted relative to the boss 19 to regulate the movement of the arms223 toward each other. 27 indicates a coiled spring mounted at its endsupon the arms 2223 tending to hold said arms against movement away fromeach other. 2829 (see Figs. 1 and 2) are knife blades secured by screwsor in any other suitable manner to the arms 2223, respectively. 3031indicate guides adjustably mounted upon the arms 22 23 alongside theknife blades 28--29, respectively, said guides extending forward andoutward from the cutting edges of said blades, as best shown in Fig. 2,said guides by reason of contact with the car as it is fed through themachine serving to move the knife blades apart into proper position forcutting the kernels from the cob whatever may be the size of the ear,the guides 303'l being adjusted relative to the blades in accordancewith the size of the kernels of the corn being treated. 32-32 indicatespur rollers revolubly mounted slightly in front of the blades 2 29 butdirectly adjacent thereto, said spur rollers being oppositely disposedand driven in any suitable manner for feeding the ears between theblades will be readily understood.

Referring now particularly to Fig. 6, which shows the complete system ofcutting blades as I prefer to embody them, 33, 34c and 35 indicatesadditional. brackets mounted upon the bar 10 and the plate 11 in thesame manner as is the bracket 12 mounted thereon. The bracket 38 hasmounted upon it arms 3637 in the same manner as are the arms 2223mounted upon the bracket 12, being yieldingly held together in normalposition by a spring 38. 39-40 indicate the guides adjustably mountedupon said arms 36-37, and il4.-2 indicate the blades mounted upon saidarms in horizontal posi-v tion. The bracket 34 in turn is likewiseprovided with arms L34d connected by a coiled spring Said arms areprovided with guides ec r7, respectively, located alongside of thediagonally positioned blades et8l9, such blades being approxr mately atright angles to the blades 28-29 mounted upon the arms 2223. The bracket35 in turn is likewise provided with arms 50-51 connected by a spring52. Said arms 505l are provided with guides 53 54, adjustably mountedthereon alongside of blades 5556, respectively, said last-named bladesbeing mounted in vertical position.

57 indicates spacing blocks mounted upon the bar 10 for properly spacingthe brackets 12333d35 upon said bar 10.

1 rom the above description and from a reference to Fig. 6 it will beseen that the cutting portions of the several pairs ofoppositely-disposed blades lie on opposite sides of alongitudinallyextending line passing through the point marked A in saidfigure. It will be understood that an ear of corn will be fed to theblades along the line indicated by A, being forced into contact with therespective blades by suitable pairs of spur rollers similar to therollers 3232 driven in opposite directions by any suitable means, a pairof such rollers being located between each two adjacent pairs of cuttingblades. It will be understood that as the ear approachesa pair of bladesthe ear first engages the guides extending in advance of the blades,serving to separate the knives the required amount against the action ofthe spring by which said knives are held yieldingly together. I havefound in practice that by the use of my improved construction the cornis cut evenly all around to much greater advantage than can be done bythe use of curved blades.

In Fig. 7, which shows a modified construction, I have indicated thecorresponding parts by the same reference numerals, but with theaddition of an exponent a. In this figure, 58 indicates a bracketm0unted upon the bar l0 and the plate ll just as are the bracketsheretofore described.

5960 indicate arms mounted upon the bracket 58 ust as the arms 22-23 aremounted upon the bracket 12, said arms 596O being yieldingly heldtogether by a spring 61. 6263 indicate guides adjustably mounted uponthe arms 5960, respectively, and G l 65 indicate the cutting bladesmounted upon said arms. 6667 indicatea second pair of arms likewisemounted upon the bracket 58 and held yieldingly together by means of thespring 68, Gil- 70 indicate guides adjustably mounted upon said arms66-67, respectively, and 7172 indicate cutting blades mounted upon saidarms adjacent to said guides. It will be understood that the bracket 58may be substituted for the lllO brackets 12 and 81 in a machine adaptedfor its use. It will likewise be understood that another single bracketmay be substituted for the brackets 3335 if desired, the ultimate effectof the modified construction being sub stantially the same as that shownin Fig. 6 except that in the use of the modified construction it wouldnot be possible to remove from the machine a single pair of the bladecarrying arms. Moreover in the modified form of construction only asingle pair of spur rollers would be used with each two pairs of cuttingblades instead of a pair of such rollers with each pair of cuttingblades.
